Execution Reverted

Description

This error occurs when a contract attempts to access data that is missing or undefined in the destination contract. Typically, this happens when the destination contract is either not deployed on the target chain or does not implement the expected entry function.

In the LiquidsFi Explorer, the error may appear as follows:

execution reverted (no data present; likely require(false) occurred (action="estimateGas", data="0x", reason="require(false)", transaction={ "data": "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", "from": "0x16B247ddd0B1B56A667aF7715FEABf61Bc18ec70", "to": "0x764edea8412F67d0c39119e50096813ED3879D62" }, invocation=null, revert=null, code=CALL_EXCEPTION, version=6.15.0)

Example

In this particular transaction:

• msg_id: 0xa806dbd8386046e7edbf4eed5625c828f9f55e466cd9046e30a1206032d0e7c3

• Origin Chain: 12000000 (Soroban)

• Destination Chain: 35000000 (Ethereum Sepolia)

• Destination Contract: 0x4F0b566329d8031e54ED963F092A320009295dfB

This error occurs because the destination contract either:

1. Is not deployed on the Ethereum Sepolia, or

2. Does not implement the LiquidsFi Oracle entry function expected by the Oracle contract.

How to Fix

1. Verify Contract Deployment: Ensure the destination contract is deployed on the correct destination chain.

2. Implement the Oracle Entry Function: Confirm that the contract includes the required onOracleData function:

function onOracleData(bytes calldata data) external onlyOracle {
    // decode data
    // custom code to handle the oracle data
}

Notes

The onOracleData function serves as the entry point for LiquidsFi oracle data. Missing or incorrectly implemented functions will cause transactions to fail with the “missing revert data” error.
