Trusted by the companies you know
From multichain wallets to onchain apps — teams build on Zerion API.
“Zerion API powers Kraken 2.0 with reliable token balances, P&L, and transaction history through one consolidated integration, making it easier to scale to more users.”
“We've worked with Zerion API since day zero, even before launching Uniswap Wallet. From multichain positions to EIP-7702 batching, they've been key partners.”
“We use Zerion in production across the Base App, from transaction history to real-time PnL. It's scaled with us from the first rollout to millions of users, including our expansion to Solana. The data just works, and their team moves as fast as we do.”
“Zerion's transaction and portfolio APIs power Privy's wallet experience. Everywhere we show wallet balances in the dashboard is powered by Zerion. Their reliable data has given our engineers the speed and reliability to deliver a core part of Privy's value to developers.”
