Solana Blockchain v6.1.5

Release Date: October 1, 2026 Tags: WITHDRAWALS, SPL TOKENS, SOLANA

Overview

A token withdrawal could be refunded after the network had already accepted it. When the request that submits an SPL token transfer failed — a timeout, a rate-limit answer — the withdrawal was marked failed and the customer refunded, although the transfer may already have been relayed. Native SOL withdrawals already checked the cluster in that situation; token withdrawals now do too.

The network-label fix for installs on devnet or testnet, and its repair command, ship with Core v6.8.2; its notes say who needs them.

No new dependency: requires Core v6.7.9, as before.

Update Instructions

pnpm updator

No schema change, no seeder, no .env change.

Upgrade Notes

Token withdrawals that now wait for you

• A token withdrawal whose submit errored and that the cluster cannot confirm either way is held as status-unknown for manual review, not refunded. Check its signature on the cluster and resolve it by hand.

Fixed

Token withdrawals refunded after they were sent

• Fixed an SPL token withdrawal being marked failed and refunded when the submit request errored after the network had already accepted the transfer. The transaction's signature is now looked up on the cluster first: found means the withdrawal carries on as sent, a clear refusal means failed, and anything unclear is held for manual review.
