Hey looking for an alternative to getSIgnaturForAddress which is not limited by 1000 signatures (from newest-old) i wanted to know if there is a way to fetch the entire tx hashes/signature from the time the contract got developed.

AFAIK there's no such function. getSignaturesForAddress returns the transactions in order, newest first. It also takes an optional before parameter, which can be used to fetch the 1000 transactions before a given signature. So the best thing to do is to write a loop/recursion, which passes the last transaction signature as before if you fetch all 1000 transactions.

There's a good example of this in the Solana Pay codebase: https://github.com/solana-labs/solana-pay/blob/master/core/src/findReference.ts#L25 This function is getting the oldest signature for a given address, but it's the same idea.

There is no native function at the moment, but you can do something like this:

function getAllTxForAcc(myAcc, connection){
    const batchSize = 1000;
    const res = [];
    let fetched = await connection.getConfirmedSignaturesForAddress2(myAcc, { limit: batchSize });

    // We know we've ran out of sigs when the fetch 
    //returns less sigs than we asked for
    while(fetched.length === batchSize) {
        fetched = await connection.getConfirmedSignaturesForAddress2(
            myKey, { 
                limit: batchSize, 
                before : fetched[fetched.length-1].signature 
            });
        // This can be cleaned up to actually create an array of 
        // sigs rather than array of array of sigs. Left 
        // as an exercise to the reader ;)
        res.push(fetched);
    } 
    return res;    
}

    I don't think this will work because you're never passing a before parameter to getConfirmedSignaturesForAddress2. If there are >1000 transactions then the fetch will always return the latest 1000 transactions and the loop will never terminate.

    You're correct, I've adjusted my answer
