I built three tools that turn a Self name into an address outside Self's own dashboard.
What I built
A MetaMask Snap: type alice.self into MetaMask's send field and get Alice's address for that network. It's in MetaMask's directory of verified Snaps, though the listed version no longer resolves names.
A TypeScript SDK, @selfcrypto/sdk, that resolves a name to its owner, its address on another chain or its full profile (docs), and the small API the Snap calls. The source is public: selfcrypto/self-snap and selfcrypto/sdk.
