Testnet Smart Contract (natSpec)

All locking, reward distribution, and additional locking operations for Sequencers are executed on the Sepolia Testnet. These contracts are integral to managing the Sequencer lifecycle and ensuring smooth participation in the network.

Key Contracts

The following contracts are essential for Sequencer operations:

Contract	Address
LockingInfo	0x390A6fE63385522E87e248BC5200f7d3a02F994b
LockingPool	0x7591940125cC0344a65D60319d1ADcD463B2D4c3

Sequencers can perform all operations, including managing rewards and lock-ups, directly through these contracts without needing frontend access.

Key Contract Functionalities

The following methods are provided to manage Sequencers efficiently. These include querying and updating your Sequencer's status, locking tokens, and handling rewards.

Write Contract Information

1. lockFor

   • Locks METIS tokens and assigns Sequencer ownership.

   • Parameters:

     • _signer (address): Sequencer signer address.

     • _amount (uint256): Amount of METIS to lock.

     • _signerPubkey (bytes): Uncompressed public key of the signer.

2. lockWithRewardRecipient

   • Similar to lockFor, but allows specifying a reward recipient at the outset.

   • Parameters:

     • _signer (address): Sequencer signer address.

     • _rewardRecipient (address): Reward recipient address.

     • _amount (uint256): Amount of METIS to lock.

     • _signerPubkey (bytes): Uncompressed public key.

3. relock

   • Adds additional tokens to an existing lock or locks accrued rewards.

   • Parameters:

     • _seqId (uint256): Sequencer ID.

     • _amount (uint256): Amount to relock.

     • _lockReward (bool): Whether to lock rewards.

4. setSequencerRewardRecipient

   • Updates or assigns a reward recipient for a Sequencer.

   • Parameters:

     • _seqId (uint256): Sequencer ID.

     • _recipient (address): New reward recipient address.

5. withdrawRewards

   • Withdraws accrued rewards to the specified address.

   • Parameters:

     • _seqId (uint256): Sequencer ID.

     • _l2Gas (uint32): Gas limit for the operation.

6. unlock

   • Initiates the unlocking process for METIS tokens.

   • Parameters:

     • _seqId (uint256): Sequencer ID.

     • _l2Gas (uint32): Gas limit for the bridge operation.

7. unlockClaim

   • Claims unlocked tokens after the 21-day waiting period.

   • Parameters:

     • _seqId (uint256): Sequencer ID.

     • _l2Gas (uint32): Gas limit.

8. withdraw

   • Partially withdraws locked tokens, ensuring the remaining balance meets the minimum lock requirement.

   • Parameters:

     • _amount (uint256): Amount to withdraw.

     • _seqId (uint256): Sequencer ID.
