TipLink

TipLink (rebranding to Fin) is a Solana-based Web3 infrastructure company founded to make transferring digital assets as frictionless as sending a link. Founded in the early 2020s and backed by Sequoia, Multicoin Capital, Circle Ventures, Solana Ventures, and Pantera Capital (Series A, $17M), TipLink has built a suite of developer tools and APIs that enable businesses and developers to distribute, manage, and transact with digital assets on the Solana blockchain.

Core Products/Services

TipLink's product suite centers on programmatic wallet infrastructure for the Solana ecosystem. The TipLink API allows developers to programmatically generate non-custodial wallets that hold SOL, SPL tokens, NFTs, and SFTs at scale. TipLink Pro (TipLinkClient) is an enterprise-grade API and dashboard enabling organizations to create distribution campaigns with dispensers, track analytics, and manage large-scale digital asset airdrops and giveaways. The TipLink Wallet Adapter is an SDK for Solana dApp developers to embed a Google-login-based self-custodial wallet into their applications, enabling Web2 user onboarding without seed phrases, browser extensions, or app downloads. Email TipLinks provide a secure enclave-based API for sending Solana assets directly to recipients via email.

Key Strengths

TipLink's core innovation is eliminating the onboarding friction of Web3 by enabling wallet creation with just a Google account. Their non-custodial architecture means TipLink Corp never holds users' private keys. The use of AWS Nitro Enclaves for Email TipLinks ensures private keys remain secure even during email delivery. The platform targets both Web2 users (no crypto experience required) and Web3 developers who need scalable asset distribution infrastructure on Solana.

Notable Clients/Projects

TipLink has been used for large-scale NFT giveaways, digital collectibles distribution, Solana Pay checkout integrations, and token distribution campaigns. The platform supports use cases including merchandise souvenirs, digital raffles, loyalty tokens, and peer-to-peer payment flows. The company announced a rebrand to Fin in late 2025, positioning itself as a next-generation stablecoin payments platform.

Why Choose TipLink

TipLink offers the only Solana wallet infrastructure that requires zero Web3 knowledge from end users—recipients need only a Google account. The developer API is available via NPM (@tiplink/api), well-documented, and supports programmatic generation of thousands of wallets for enterprise distribution campaigns. For dApp developers, the Wallet Adapter provides a composable integration path that dramatically improves conversion rates by removing the browser extension requirement.
