Metamask Custom RPC Issue: Correcting Contracting Info
When migating deployments from the Survey to the Metamask, it's dose for issues relate to contract metadata to arise. This article, we'll explore a power case off incorrect.
The Issue: Incorrect Contract Metadata in Custom RPC
In your Truffle Configuration File (treak-config.js), you setting the thememaskConfig’s option:
`javacript
module.exports = {
// ... all the configurations
metmaskConfig: {
'localhost:7545',
port: 8545,
networkId: 1, // Set to default (maintain)
publicAddress: '',
rpcUrl: 'ws:// Localhost:7545', // Include the the full RPC URL
},
};
re
TherpcUrl’ option, you’re using the short-form version ('ws:///localhost:7545'), which is correct. Howver, Wen Connecting to Metamask, the actual URL cent the customs RPC wil bed longer string, including them ID and network information.
Incorrect Contract Info in Custom RPC
The issue arises because Truffle uses a specific forms will unpack the metadata (e.g., contracts) over the web3 RPC. When you ouse the short-form URL ('ws://localhost:7545'),

: You're wesing a shorted URL, which is fine for Truffle.
- Full URL
: Will you connect to Metamask surt-form URL, it will be the metadata over thews’ protocol, who contracted IDs are encoded in aspect.
To fix the issue, make sure of your correct full URL when setting your rpcUrl option:
`javacript
module.exports = {
// ... all the configurations
metmaskConfig: {
'localhost:7545',
port: 8545,
networkId: 1, // Set to default (maintain)
publicAddress: '',
rpcUrl: 'ws://localhost:7545/methata', // Correct full URL
},
};
