Description

AccountId is a string representing a NEAR account. This string should be between 2 and 64 characters. There are
additional requirements such as limited use of alphanumeric characters and separator characters.

There are a number of external smart contract functions in aurora-engine which BorshDeserialize an AccountId without validating it.

  • implement the missing account validations
  • Adding extra tests to cover some edge cases.

### Added

- Enabled XCC for mainnet release by [@birchmd]. ([#694])
- Added `set_owner` contract method which sets the owner of the contract
by [@hskang9]. ([#690])
- New variant of submit function `submit_with_args` which accepts
additional arguments along with the transaction such as the max gas
price a user is ready to pay by [@aleksuss]. ([#696])
- Added the ability to create and fund XCC sub-accounts from external
NEAR accounts by [@birchmd]. ([#735])

### Changes

- Replaced `rjson` with `serde_json` by [@aleksuss]. ([#677])
- Changed owner intended contract methods to now require owner or the
contract itself by [@hskang9]. ([#676])

### Fixes

- Fixed nonce incorrectly being incremented on an out of fund failure by
[@joshuajbouw]. ([#671])
- Fixed a check in promise results before executing cross contract calls
(XCC) callbacks by [@birchmd]. ([#693])
- Fixed a reachable panic in `receive_erc20_tokens` by [@0x3bfc].
([#709])
- Fixed a lack of minimum size checks when instantiating a new `EthGas`
object by [@lempire123]. ([#722])
- Fixed a lack of division by 0 checks in `EthGas::Div()` by
[@lempire123]. ([#718])
- Fixed the validation of the return of `exports:storage_remove` by
[@0x3bfc]. ([#712])
- Fixed missing account validations of NEAR account IDs by [@0x3bfc].
([#703])
- Fixed a reachable panic in the `exitToNear` and `exitToEthereum`
precompiles if the input amount is greater than 1^128 when cast from a
`U256` to `u128` by [@0x3bfc]. ([#681])
- Fixed a reachable panic in `modExp` due to arithmetic overflow by
[@0x3bfc]. ([#688])
- Fixed the ability attaching values to Aurora specific precompiles,
this no longer is possible, by [@0x3bfc]. ([#714])
- Fixed a return error if an ecrecover signature length is not exactly
65 by [@0x3bfc]. ([#717])
- Fixed size checks on input array passed to `exitToNear` and
`exitToEthereum` precompiles by [@0x3bfc]. ([#684])
- Fixed missing gas costs in `exitToNear` and `exitToEthereum`
precompiles by [@lempire123]. ([#687])
- Fixed a reachable panic due to out of memory in the `modExp`
precompile by [@0x3bfc]. ([#689])
- Fixed an assurance that the `sender_id` has a balance greater than the
amount in `ft_transfer_call` by [@0x3bfc]. ([#708])
- Fixed returning `0x` when a length cannot be cast as `usize` instead
of returning an error in the `modExp` precompile by [@birchmd]. ([#737])
- Miscellaneous minor fixes by [@0x3bfc]. ([#738])
