## DeFi

### 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
