Turn Weeks of Transaction Debugging Into Minutes

Transaction debugging should be quick

The Solana ecosystem makes transaction debugging a long, painful process. For complex transactions, developers have to

inspect logs to pinpoint error causes

(hours)


develop mocks and fixtures to replicate state

(days)


set up multiple test frameworks for different cases

(weeks)

But diagnosing a transaction error should be as simple as: tell me what happened and where.

And it's about to be.

Introducing Seer

launch Seer RPC

(1 click)


run seer build

(seconds)


run tests on Seer RPC

(minutes)

The Seer RPC is a drop-in replacement for solana-test-validator, testnet, or mainnet RPCs.

Every transaction in your test generates a full transaction trace, with mappings to source code, including mainnet contracts, and variable values at the time of execution.

Every transaction error comes with the exact line, exact state, and exact backtrace in source code.
