Permissioned paths
Run the admin path you don't have keys for.
Patch a pool admin, vault manager, or program upgrade authority to your wallet. Walk the CPI tree locally.
Use cases
What people build with Reley.
Anything the live chain refuses or makes slow. Permissioned paths, upgrade dress rehearsals, oracle edge cases, CPI integration tests, CI without quotas.
Mint anything
Mint USDC, BONK, or any token to your wallet.
Flip mint authority on a cloned mint. Fund test scenarios with as much liquidity as you need.
Replay + debug
Re-run a failed mainnet tx with a debugger.
Hydrate at slot - 1, execute locally, compare account diffs and CU per frame against the chain.
Edge cases
Push oracles to extreme prices. Force liquidations.
Set Pyth / Switchboard feeds to any value. Test how your program behaves at the edge of its config.
Upgrades
Test the new program before you redeploy.
Clone live state, swap in the new program, replay top traffic. Catch regressions before mainnet does.
CPI integration
Wire your program against any protocol locally.
Clone Meteora, Kamino, Jupiter, Drift, anything. Build the CPI path, simulate, ship with confidence.
Workflows
Reproduce bugs your team can re-run with one click.
Stack airdrops, warps, snapshots, txs into a script. Share the sandbox as a JSON-RPC URL.
CI + tests
Run integration tests without RPC quotas.
SVM sandbox boots in milliseconds. No archive node, no rate limits, no shared state.
Use case
Test the admin path
you never had keys for.
Your program CPIs into Meteora's DLMM. The pool admin is a Meteora-controlled key. The integration path you actually need to exercise is the one only that key can call.
Reley clones the pool, the vaults, the oracle, every bin array, every mint. Then it patches pool.admin to your local wallet. The CPI tree runs. You see compute, logs, and account diffs at every frame.
Same shape for Kamino vault managers, Drift insurance authorities, Jupiter route ops, any permissioned PDA on mainnet.
