Fixes in plugin API: metadata is now json-encodable, fixed calling product creation hooks, better UI slots in store

Plugins support

It's finally here! Starting from this new major release series, BitcartCC is now fully extendable!

Anything is now possible

Server admins can now install plugins from the UI.

Just upload a plugin archive (.bitcartcc extension), and it will automatically re-build everything!

It is possible to customize backend (by adding new pages, database tables or adding metadata, hooks and filters), UI (new pages, extend in special UI slots, add new data), and docker deployment (new auto-loaded components and rules).

The opportunities are limitless!

See example here: https://github.com/bitcartcc/bitcart-plugin

The plugins support will get extended over time.

We encourage all plugin authors to start working on their first plugins, we will issue follow-up releases polishing the API

Anything that has ever been requested before which didn't fit well in BitcartCC core can be extracted to a plugin!

Tx hashes of paid invoices in UI

A commonly requested feature, now you can view (and even instantly view in block explorer) tx hashes of paid invoices.

New algorithm for detecting payments in ETH

While our current ETH support is great and previous method (unique amounts) seemed to be the most optimal one with zero costs to the merchant, it actually incurred some costs: costs for customer support to handle cases with users sending not exact amounts. This is not greatly automated.

That's why, we came up with a new way: ask customer for the address they will be sending from.

This allowed us to process payments in the same way as in other currencies, it even allows invoice to be paid in parts. If user over-pays, there is no issue anymore.

Checkout UI for eth-based currencies was reworked to present user with 3 choices: enter address manually, or pay via metamask or walletconnect (address gets pre-filled).

Monero support

This release includes the long-awaited monero support!

This means that now BitcartCC supports all major coins and no other solutions are needed to accept payments

For now, payouts support and balance fetching is disabled for monero because it is not yet clear how to do that in a light-weight environment.

For it to work, just enter your secret viewkey and address, and enjoy!

We use integrated addresses to detect payments.

Cleaner payment methods selection

Before it was not obvious that you can switch between currencies in admin panel's checkout UI. By adding a special icon, it is now way clearer

Monero support Added new argument --address to specify monero wallet's address

Extreme speed

Due to the cutting-edge optimizations, invoice creation, balance fetching and other operations are up to 10x faster

Captcha support

You can now protect login pages with hcaptcha. It is configurable in server policies. Login and registration pages will be protected and less spam will be possible

Better stability

ETH daemon implementation is applying proper retry logic in more places, allowing for no blocks skipped due to temporary network errors

Fixed some crashes when processing a lot of wallets

Misc changes

• Python 3.11 support
• Fixes for random selection of wallets
• Make it possible to make auth mandatory in invoice creation
• Disable EIP1559 in eth for more predictable fees and add COIN_TX_SPEED to configure default gas price being used in transactions
• Fix duplicate websocket notification sent from the daemon
• Display store name in store POS page title

Fix ETH-based daemons transaction processing

Fix admin panel's dialogs UI

This update includes Groestlcoin (GRS) support, as well as fixes for Tron RPC and allows to use Ankr RPCs for ETH too.

WalletConnect button

While our current ETH support is great, many users may still get confused and send wrong amounts when not using metamask wallet.

On checkout there is now a new button available: Pay via WalletConnect. Users can then scan a QR code to connect their wallet, BitcartCC will do the rest

Tron support

The long-requested Tron (TRX) support is there! It is supported fully and in a similar way to how ETH works. Each method have been implemented and tested.

BitcartCC might be even the only software which implemented the full transaction fee calculation algorithm except for full node itself. You can know the fee before sending via get_default_fee command.

Note: the volume of transactions in Tron network is way higher than in ETH or even BNB, but we found a solution to make it work under high loads. The only downside is that you should not keep your node offline, ideally try to never let it be offline for more than few minutes.

Tron (TRX) support

Block explorer support

You can now instantly view tx hashes of your payouts (and invoices in the future, too) via block explorers.

BitcartCC provides a list of sane defaults, but you can easily customize for your own

Randomize wallets used setting

For better privacy, UX and funds distribution, if you have multiple wallets of same currency connected, you can now enable a setting, and in invoices only one random wallet will be picked, not each of them

Allow searching by payment methods

Ever needed to search by address of your invoice? It is now possible!

Polygon (MATIC) support

Polygon is now supported

CRITICAL: fixed exchange rate issue

Exchange rate issue introduced in 0.6.8.0 release series is finally fixed. Thanks to everyone who helped to coordinate a fix!

Drop arm32 support

We no longer build arm32 images. You can build them from source if you still use arm32

CLI improvements

Our bitcart-cli have been improved greatly! You can now pass keyword arguments, i.e.

bitcart-cli payto address amount --feerate

Also, better output was added in some cases.

Autocompletion is now available! Just press tab as usual, and you will be hinted the list of CLI commands supported

Also, you can get full help on any command like so now:

bitcart-cli help payto

Misc changes

• Fixes for tor support in onedomain mode
• Added new settings for admin and store to allow integration to Citadel: BITCART_ADMIN_ONION_API_URL and BITCART_ADMIN_ONION_HOST. This allows skipping reading the hostname file and using env var as a source of tor hostname

Our bitcart-cli have been improved greatly! You can now pass keyword arguments, i.e.

bitcart-cli payto address amount --feerate

Also, better output was added in some cases.

Autocompletion is now available! Just press tab as usual, and you will be hinted the list of CLI commands supported

Also, you can get full help on any command like so now:

bitcart-cli help payto

If using CLI not in our docker deployments, please follow this guide on how to install autocompletion

Payouts support

Yes, now it is possible to send payouts right from BitcartCC's admin panel!

For clarity, BitcartCC core supported this from day one due to our modular stucture, and now it is available at the highest level in BitcartCC: the UI.

A new tab was added to dashboard. Why is it useful? Because managing and opening wallets for many currencies is not convenient when you can do this from BitcartCC's unified UI. Send payouts, see tx hashes of sent transactions, limit fee usage by transaction, review payouts and see used fee stats!

If a wallet is a hot wallet, payouts are signed automatically. But most wallets in BitcartCC are watch-only.

You will be able to enter a private key for signing operations. It won't be saved anywhere on disk or shown in any commands output.

This is possible due to new mode in the daemon: diskless (in-memory) mode. Read below for details

Diskless mode

For some operations, like signing, sometimes you have to use a private key. But it is not good when a wallet is cached to disk, together with all keys and wallet history. That's why we added a new mode to the daemon.

When from SDK, send diskless: True param as part of xpub's dict, i.e. {"xpub": "seed here", "diskless": True}

You can use such a mode from CLI like so:

bitcart-cli --diskless -w "seed here" signtransaction txdata

Fixes to rounding of amounts

Now final, the way BitcartCC rounds amounts is stable. Now amount you see in the UI match the exchange rate displayed, and a bug where you could send exact amount and it still wouldn't be detected is fixed now

Misc changes

• Fixed deployment's ssh key generation to a newer algorithm
• Cloudflare tunnel support
• Boxbilling plugin

• --contract flag to load wallet with contract key passed to daemon

• --diskless, -d to enable diskless mode (don't store wallet files on disk)

Hotfix release: if you ssh to your server as root user, it could have been broken by 0.6.8.0 release. This is fixed now.

Please run chown root /root/.ssh/authorized_keys if it got broken.

Also added ability to customize API title and openapi file

docker-compose v2

BitcartCC now uses docker-compose v2. It's faster and more secure. BitcartCC should try to update docker-compose automatically. All container names are now separated by - and not _. Example: if before you would use compose_backend_1, now it's compose-backend-1

Secure images

All BitcartCC images are now built in a way that non-root user runs processes inside a container, helping avoid some docker vulnerabilities and making whole BitcartCC stack more secure. This also means less workarounds our side.

Electrums upgrade

All electrums were upgraded to 4.3.0+. Minimum required version to run BitcartCC is now python 3.8+, base image version is now 3.9

Other changes

• Onchain payment of same amount no longer can trigger contract payment confirmation
• BitcartCC should now properly install itself on Mac os, even M1 arch.
• Fixed a bug on binancecoin where exchange rates weren't fetched
• Added ability to pass --contract flag to bitcart-cli to load a wallet with a specific contract
• Fixed domain-less usage of BitcartCC via tor
• Fixed a bug where worker wouldn't start after deploy without a restart

Fixes gas estimation to work 100% of the time

Now contract payments don't get stuck on first error but will always get detected

Added retry mechanism to eth daemons - no temporary issues should ever interrupt payment processing!

Proper params casting + transfer function now accepts amount in ETH, not wei (and it does proper casting to needed divisibility by itself!)

No more server error on PATCH when you only pass i.e. wallets

New daemon method for eth-based coins: get_default_gas - it gets the gas value needed to execute a transaction. Before it was named get_default_fee. Now the get_default_fee method behaves like it did in other coins: it returns amount needed to pay the fees

Added ability to configure number of hours eth-based daemons can be left down (default: 1 hour). Configurable via COIN_MAX_SYNC_HOURS env variable.

For ETH, BNB and all the contracts the maximum number of decimal digits is artificially decreased to 8 decimals. That's because most exchanges and software doesn't support more than 8 decimals (noone's following the specs except for us), so to make it possible to send from i.e. binance this change was made.

Daemon is almost unmodified - it stores and returns balances in original 18 decimals precision, just that invoice amounts generation algorithm will use at max 8 decimals. As for the merchants API, the output formatting decimals were indeed changed to 8 (from 18), so checkout page now has 8 decimals, which is more readable.

Better UI for final statuses on invoice page

Simplified payment process via metamask: just one button state (pay via metamask) instead of separate connect/pay flows.

Smart contracts balances are now properly displayed in the admin panel

Fixed metamask icon loading

Fixed a rare bug in token payment processing

The create backup button now automatically downloads newly created backup, so you no longer need to access your server to get it saved locally!

Better checkout on eth-based payment methods on desktop: added pay via metamask button

Fix eth payment methods onchain qrcodes (put amount in wei)

There is also a message displayed telling customers to pay exact the needed amount

Also you can now customize the checkout hint for any wallet (payment method) you need

Shopify integration

It is now possible to connect BitcartCC to your shopify stores! Check the shopify integration icon on stores page and our docs for more details

Better invoice export

For better accounting, invoice export process have been improved.

The export button now has a dialog which allows to customize more options! By default it no longer includes payments as they were quite useless and added lots of unneccesary fields

There is a new "All users" option to export all complete invoices by all users (available only to server admins, this is useful for instances taking fee percent from transactions without interferring into payment flow)

Use current query allows you to apply some filters using the search bar (and sorting by columns), and then export that data

Normalize contract addresses: no matter where you've got contract address from, it should correctly detect payments now.

Upgrade is recommended for everyone accepting contract payment as before that fix payment processing maybe didn't work for you.

Please re-save all existing wallets with contracts for them to be normalized.

Added more bep20 tokens to pre-defined list

Better exchange rate normalization: it should now correctly work for coins with low exchange rates and in some edge cases

SmartBCH support

Fix BCH payment processing

Better handling for long currency names in checkout page
