Smeltr

Non-custodial Token-2022 deployment infrastructure for Solana.

The non-custodial guarantee: Smeltr builds transaction instructions. Your wallet signs them. assertNoPlatformAuthority() runs on every authority field in every module before any instruction is constructed, and the source for that check lives in packages/module-registry in this repository — the guarantee is inspectable, not just asserted.

Extensions: Transfer Fee · Non-Transferable · Permanent Delegate · Arweave metadata
