Nonce API #205
Description
Description
Create a get nonce API endpoint such that blokli returns the nonce for the next pending transaction
There should be a new query API that simply returns next Nonce for a given address, e.g.:
"""
Retrieve next transaction Nonce for any Ethereum address
This query returns the next Nonce for any address type:
1. For EOAs (Externally Owned Accounts): Returns the next nonce by inspecting the transaction count and pending txs in the mempool
2. For Safe contracts: Returns the Safe's internal nonce via nonce() function
3. For other contracts: Attempts nonce() call, falls back to 1.
The transaction count increments with each transaction confirmed or rejected by the address.
Returns Error with code INVALID_ADDRESS if address format is invalid.
Returns Error with code QUERY_FAILED if blockchain query fails.
"""
nextNonce(
"Address to query (hexadecimal format) - supports EOAs and contracts"
address: String!
): NextNonceResult!
"""Nonce information for any Ethereum address"""
type NextNonce {
"Address queried (hexadecimal format)"
address: String!
"Next nonce for the address"
count: UInt64!
}
"""Result type for next noce queries"""
