The EVM Lambda and our Patch component are two of the core components used to instrument the chain and run off-chain computations based on on-chain events. We've received many questions about both and when to use them.

The quick answer is: it depends. Each has its advantages:
• Lambdas are more flexible: : You can insert execution across many contracts (e.g., those that share an ABI), upon each transaction, each storage write, or each block. None of these is possible with Patch.

• The Patch on the other hand, puts you within the contract: If you're interested in a single contract, and particularly if you'd like to emit transient values from it, Patch is very powerful.
