Release

Release Name: 4.44.0
Spec Version: 44
Client Version: 4.0.0

Key Changes:

• Fixed an issue in gas calculation of the ERC-20 precompile, it's now charged the correct amount
  • transfer should cost ~ 317,060 drops
  • transferFrom should cost ~ 358,396 drops
• Added an admin extrinsic set_length_multiplier that allows us to control the gas scaling by the length of the transaction
• Added public mint functionalities for NFT and SFT pallets. This allows any account to mint tokens from the enabled collections
  • Disabled by default, needs to be enabled with toggle_public_mint extrinsic
  • Mint fee can be set with set_mint_fee extrinsic
• Added Vortex token distribution pallet. This allows for the distribution of Vortex tokens at the end of a 90 day cycle.
  • Asset prices are calculated off chain and provided with the use of an admin function set_asset_prices
  • Token distribution amounts can be specified per account with the admin function register_rewards
  • Vortex distribution calculated and tokens minted through the admin function trigger_vtx_distribution
  • Vortex payout enabled through the use of an admin function start_vtx_dist
  • Users can claim their tokens manually through the extrinsic redeem_tokens_from_vault
• Enabled bridging of ROOT token through existing ERC20-Peg. This differs from standard ERC20 bridging as it will transfer tokens to and from the erc20-peg pallet address rather then burning / minting on demand
• Disabled submit_challenge extrinsic on ETH bridge

Testing Recommendations:

ERC-20 Precompile

• transfer and transferFrom should charged the right amount

NFT and SFT

• Regression testing for standard minting should be unchanged for existing collections (Without public mint enabled)
• Public mint functionality with specified mint fee should work for existing and new collections if enabled (Both NFT and SFT)

Ethereum / XRPL Bridge

• Regression testing for standard ERC20 tokens bridging (Deposit and Withdraw)
• Regression testing for XRPL bridging (Deposit and Withdraw)
• Bridging ROOT token to new ROOTPeg contract (Deposit and Withdraw)
• submit_challenge extrinsic for ethBridge should fail

Vortex Distribution

• Vortex token distribution should work with specified asset prices and registered rewards
  • Should payout correctly over more than 100 accounts
