It is obvious that for further AMB adoption it could be a situation when one chain concentrates several AMB contracts of the same nature. Even for now there are two...
This issue is being opened to make research to identify ability of migrating a native-to-erc bridge (e.g. WETC bridge) to be an extension of AMB bridge. The following is required...
In order generalise the name of the repo it is being suggested to change the name to `tokenbridge-contracts`. This issue is opened to track the work required to change the...
As part of #295 two ways to transfer tokens with specifying an alternative receiver were implemented: 1. for scenarios where generic ERC20 tokes are involved it is necessary to use...
All three bridge mode (`native-to-erc20`, `erc20-to-erc20` and `erc20-to-native`) operates with absolute daily limits. For example, if the limit for the xDai bridge is equal `100000` xDai it means that if...
After addressing [Alternative receiver in ERC20-to-NATIVE mode](https://github.com/poanetwork/poa-bridge-contracts/issues/296) and [Alternative receiver in NATIVE-to-ERC20 mode](https://github.com/poanetwork/poa-bridge-contracts/issues/297) it will be more easy to send tokens from a contract on one chain to an EOA...
At [this particular moment](https://github.com/poanetwork/poa-bridge-contracts/releases/tag/3.0.0) there are no daily limits for the bridge operations in the AMB mode. The current limitation is only for maximum gas usage per call. It means...
One of the view on the AMB feature in the `defrayal` mode was initially described here: https://github.com/poanetwork/poa-bridge-contracts/issues/73#issuecomment-417270208 During the implementation it was found the following security concerns: - a contract...
At this moment it is not possible to set the fallback gas price for `native-to-erc20`: https://github.com/poanetwork/poa-bridge-contracts/blob/048f51e0e8e7ce4213b727c0982aadab6c994db9/deploy/src/loadEnv.js#L225 https://github.com/poanetwork/poa-bridge-contracts/blob/048f51e0e8e7ce4213b727c0982aadab6c994db9/contracts/upgradeable_contracts/native_to_erc20/HomeBridgeNativeToErc.sol#L104 For scenarios when the validators addresses are whitelisted to be allowed send transactions...
As per the security audit there is a recommendation to explicitly limit the number of iterations assuming that it is not possible to distribute fees to number of validators that...
