Developer dividend project operation guide#

This article introduces how to participate in the contract dividend distribution project on OKTC.

How do contract developers participate in gas back?#

Note: the following operations all require OKTC to updated to v1.6.5.1 or newer.

Register for contract dividend#

To participate in the contract handling fee distribution project, firstly you will need to provide the following information for registration:

• Contract address: after registering, call this contract (initiate transaction) to proportionally distribute the handling fee dividend to the designated recipient.

• Deployer address: contract deployer. The deployer has to be this registered contract’s initiator (deployer address: that is, the currently connected wallet address).

• Withdrawer address: address of the recipient, handling fee dividend is transferred to this account; if this is not set up, the payment will directly go to the deployer’s address.

• Nonce: nonce value of the deploying contract transaction.Nonceanddeployercan accurately deduce and judge the accuracy ofcontract. The input format supports Arabic numerals, or a string of Arabic numerals separated by English commas.（i.e.,3or100,3,1,9）.

Nonce explanation：

If User1 deploys Contract1 when Nonce=5, the Nonce value will be 5 when registering Contract1;

If User2 deploys Contract2 when Nonce=6, Contract2 deploys Contract3 when Nonce=1, Contract3 deploys Contract4 when Nonce=0, then the Nonce value will be 6,1,0 when registering Contract4;

CLI

• contract: contract address. After registering, call this contract (initiate transaction) to proportionally distribute the handling fee dividend to the designated recipient.

• deployer: contract deployer. The deployer has to be this registered contract’s initiator (for the currently connected wallet address).

• nonces: nonce value of the deploying contract transaction.Nonceanddeployercan accurately deduce and judge the accuracy ofcontract. The input format supports Arabic numerals, or a string of Arabic numerals separated by English commas. (i.e.,3，100,3,1,9).

• withdraw: recipient’s address. The handling fee dividend goes into this account; if this is not set up, the dividend will automatically go into the deployer’s address.

Restrictions on participating in the Gas Back contract dividend project#

Only transactions in pure EVM format are supported, that is, transactions in which To is the contract address. Contract calls triggered by the Cosmos exchange, such as IBC, ERC20 format contracts, cannot participate in the dividend project.

The project supports contract address derivation in EVM CREATE mode, but does not support contract address deriving in CREATE2 mode.

The project supports deriving smart contract addresses from the deployer’s address, and the nonces value input cannot exceed 20 digits.
