DeFi, minusthe detours
Imagine DeFi apps without friction: easy wallet onboarding, cross-chain transactions, and accurate data pipelines. Sequence solves it all for any EVM chain.
Trusted by top EVM chains, empowering thousands of developers, and executing millions of token interactions.
Onboard
The problem
Users drop off at sign-in, get blocked without gas, or are forced into a new address for every app, resulting in fragmented assets.
The solution
One address across apps, simple zero-config auth, and built-in gas sponsorship rules so you can launch a conversion-friendly flow quickly.
- Social auth, email, and passkey sign-in with non-custodial guarantees
- Smart sessions with scoped permissions, limits, and revocation
- Seamless gas sponsorship configuration, with customizable rules
- One wallet to rule them all, securely. The end of liquidity fragmentation
Fund and earn
The problem
Users often hold the wrong token on the wrong chain. You need settlement in your currency, on your chain, without the burden of building bridges or solvers.
The solution
Trails powers 1-click cross-chain pay, fund, swap, and earn flows directly inside your app. Bridges, swaps, and gas sponsorship are handled seamlessly in the background.
- Cross-chain 1-click funding and swaps with fiat and crypto
- Deposit directly into yield vaults, from any chain, any token, using any wallet
- Swaps settle cross-chain instantly with low slippage and competitive rates
- Works seamlessly with any EVM chain, including L2s and L3s
Track and automate
The problem
You need priced balances, clean token metadata, and event-driven automations without having to stitch together multiple services.
The solution
Sequence Indexer delivers cross-chain priced balances, clean token metadata, and real-time workflows powered by webhooks.
- Single-call aggregated, priced balances across 50+ EVM chains
- Reliable token and NFT metadata with spam filtering
- 99.99% availability, sub-300ms response times for portfolio views
- Real-time webhooks with auto-retry for liquidation, rebalancing, and alerts
Secure and scale
The problem
Not all wallets are built the same. You need verifiable isolation, enforceable policies, and reliable uptime that holds steady on launch day.
The solution
Non-custodial wallets by design, with hardware-isolated signers secured by AWS Nitro Enclaves and validated on every deployment.
- Hardware-isolated signers with public attestation for every deployment
- Policy guards per transaction with session limits and revocation
- Onchain by default: time-based and private key recovery included
- Signing keys are never co-located, no social auth config needed
