World Chain is a docs-only chain on Smarts: source code and ABI are indexed, but live on-chain data (state, recent events, admin profile) is not currently available. AI agents can still query get_contract_info and get_contract_source via MCP.

Write Functions

addStake(unstakeDelaySec: uint32) payable

Adds or increases the contract's stake and sets the minimum unstake delay.✨ AI

Parameters

Name	Type	Description
unstakeDelaySec	uint32	The new lock duration before the deposit can be withdrawn.

delegateAndRevert(target: address, data: bytes) nonpayable

Delegate the provided call to a target contract and then revert using the callee's returned data.✨ AI

dev: calling this method, the EntryPoint will make a delegatecall to the given data, and report (via revert) the result. The method always revert, so is only useful off-chain for dry run calls, in cases where state-override to replace actual EntryPoint code is less convenient.

Parameters

Name	Type	Description
target	address	a target contract to make a delegatecall from entrypoint
data	bytes	data to pass to target in a delegatecall

depositTo(account: address) payable

Deposit ETH to the EntryPoint contract and credit the specified account.✨ AI

Parameters

Name	Type	Description
account	address	- The account to add to.

getSenderAddress(initCode: bytes) nonpayable

Compute the sender address that would be deployed by the provided initCode without modifying contract state.✨ AI

Parameters

Name	Type	Description
initCode	bytes	- The constructor code to be passed into the UserOperation.

handleAggregatedOps(opsPerAggregator: tuple[], beneficiary: address) nonpayable

Processes batches of user operations grouped per aggregator and executes them while crediting the beneficiary.✨ AI

Parameters

Name	Type	Description
opsPerAggregator	tuple[]	- The operations to execute, grouped by aggregator (or address(0) for no-aggregator accounts).
beneficiary	address	- The address to receive the fees.

handleOps(ops: tuple[], beneficiary: address) nonpayable

Execute a batch of user operations and transfer collected fees to the beneficiary.✨ AI

Parameters

Name	Type	Description
ops	tuple[]	- The operations to execute.
beneficiary	address	- The address to receive the fees.

incrementNonce(key: uint192) nonpayable

Manually increment the nonce of the sender. This method is exposed just for completeness.. Account does NOT need to call it, neither during validation, nor elsewhere, as the EntryPoint will update the nonce regardless. Possible use-case is call it with various keys to "initialize" their nonces to one, so that future UserOperations will not pay extra for the first transaction with a given key.

Parameters

Name	Type	Description
key	uint192

innerHandleOp(callData: bytes, opInfo: tuple, context: bytes) nonpayable

Processes a user operation with metadata and context, then returns the actual gas cost.✨ AI

Parameters

Name	Type	Description
callData	bytes	- The callData to execute.
opInfo	tuple	- The UserOpInfo struct.
context	bytes	- The context bytes.

Returns

Name	Type	Description
actualGasCost	uint256	actualGasCost - the actual cost in eth this UserOperation paid for gas

unlockStake() nonpayable

Attempt to unlock the stake. The value can be withdrawn (using withdrawStake) after the unstake delay.

withdrawStake(withdrawAddress: address) nonpayable

Withdraws available stake to the specified withdraw address.✨ AI

Parameters

Name	Type	Description
withdrawAddress	address	- The address to send withdrawn value.

withdrawTo(withdrawAddress: address, withdrawAmount: uint256) nonpayable

Transfers up to withdrawAmount of the contract's Ether balance to withdrawAddress.✨ AI

Parameters

Name	Type	Description
withdrawAddress	address	- The address to send withdrawn value.
withdrawAmount	uint256	- The amount to withdraw.
