Abstract
K2F Labs runs a production Rust SDK for Canton: canton-sdk, an async Ledger API client with DAR code generation, a typed Daml runtime, and value transcoding, and splice-sdk, a Splice application layer for the token registry, Scan, and wallet flows. The stack processes thousands of transactions on Canton mainnet, including behind Walley, a self-custodial wallet. This proposal funds turning it into a public ecosystem asset: open-sourcing under Apache-2.0 with conformance against the Ledger Client Standard, integration with the official toolchain (dpm, Canton/Splice release cadence), and a final milestone gated on adoption by independent organizations, with 35% of the request contingent on that externally verified adoption.
