TipLink

TipLink is a link-based wallet on Solana: a sender deposits SOL, SPL tokens or NFTs into a freshly generated account, and the resulting URL is itself the wallet, so a recipient can claim it by signing in with a Google account — no seed phrase, browser extension or app install. Keys sit inside AWS Nitro Enclaves, the wallet is non-custodial, recipients can withdraw to an external address, and senders can reclaim funds nobody claims. Around that primitive the team offers TipLink Pro for bulk distribution, a Wallet Adapter that lets Solana apps accept Google-login signatures, and an API that generates wallets programmatically, plus compressed NFTs for rotating QR codes used at live events and Solana Pay checkout.

In December 2025 the team renamed its consumer app Fin and shifted toward stablecoin-settled cross-border and mid-sized payments: instant transfers between users, deposits and withdrawals to bank accounts, and multi-chain stablecoin sending and receiving, with the on-chain steps hidden from end users. The TipLink-branded link wallet and developer tooling remain in operation.
