Seidar Documentation
Stellar DeFi, all in one place
Discover protocols, manage portfolios, and turn on-chain data into intelligence. Seidar brings Stellar's lending, liquidity, trading, and vaults into one non-custodial workspace.
Seidar is an all-in-one DeFi workspace built exclusively for Stellar. It gives you a single place to track your portfolio, swap assets, trade perpetual futures, lend and borrow, provide liquidity, and deposit into yield vaults — without handing over custody of your funds.
Instead of jumping between separate Stellar applications, you connect your wallet once and see your positions across supported protocols together.
What is Seidar?
Seidar is a unified gateway to Stellar DeFi. It aggregates the protocols that matter on Stellar into one interface and turns the resulting on-chain data into a portfolio view you can actually act on.
- One portfolio view across your connected wallets and supported protocols.
- One trading interface for spot swaps and perpetual futures.
- One earn interface for lending, liquidity, and vaults.
- AI analysis grounded in Stellar market and protocol data.
- Non-custodial execution — every transaction is signed by your wallet.

Supported networks
Seidar runs on Stellar:
- Stellar Mainnet — the public network for real assets and live protocol positions.
- Stellar Testnet — a sandbox for trying flows with test funds when the underlying protocol is deployed there.
There are no EVM chains or rollups in Seidar. Stellar is the product, not one chain among many.
Non-custodial by design
Seidar never holds your keys or your funds.
- You connect a Stellar wallet.
- Seidar prepares the transaction and shows you the details.
- Your wallet asks you to review and sign.
- The signed transaction is submitted to Stellar.
- Seidar reads the result from the network and updates your portfolio.
Sign-in uses an off-chain message signature. It is free, creates no transaction, and does not give Seidar permission to move your assets.
Built for Stellar
Seidar is designed around Stellar's primitives:
- Horizon for balances, payments, trades, and account activity.
- Soroban RPC for smart contract state, simulations, and events.
- Reflector for asset pricing.
- Stellar assets identified by asset code and issuer, or by their Soroban contract.
- XLM for network fees and account reserves.
The application is built with a Next.js and TypeScript frontend, Stellar wallet integrations, and a TypeScript indexing and API layer backed by PostgreSQL and Redis.
