Overview
What WebSoroban is, how signing in provisions your testnet wallet, and the edit-compile-deploy-invoke loop.
WebSoroban is a browser IDE for Soroban smart contracts on the Stellar testnet. You write Rust, compile it to Wasm, deploy it, and call its functions, without installing the Rust toolchain, the Stellar CLI, or managing a keypair.
Everything runs against testnet. There is no mainnet path, so you can experiment without risking real funds.
Sign in, get a wallet#
Sign in with Google, GitHub, or Discord. On your first sign-in, WebSoroban creates a Stellar testnet wallet for you and funds it from the friendbot faucet. You never paste a secret key or run a faucet command, the wallet exists the moment your account does.
The wallet's secret key is encrypted and stored on the server. It is decrypted in memory only at the instant a transaction is signed, and it is never sent to the browser or written to logs. See Wallets & faucet for what is stored and what never leaves the server.
Testnet only
WebSoroban talks to https://soroban-testnet.stellar.org. There is no mainnet
deploy. Test XLM has no value.
The loop#
Four actions move a contract from source to a live, callable program:
Build your crate to a Wasm binary and read diagnostics inline.
Upload the Wasm and instantiate a contract, signed by your wallet.
Call functions with typed inputs; simulate reads, sign writes.
Run cargo test and save function-level assertions against a deployment.
