Daniel Savu bf53f087c3 fix(relayer): dry-run before sending txs (#4565) ... ### Description Fixes a bug in the individual submission logic. There is a race condition where a message can become undeliverable between when it was simulated in the `prepare` step and when it's actually submitted. ### Context The bug was discovered as part of batched messages but affects chains without batching too. - when delivery fails inside batch submission simulation, we fall back to individual submission - individual submission doesn't simulate the tx outcome, and instead just submits directly - this is wrong, because the batch may cause messages to become undeliverable for long periods of time (such as when a mint cap is reached) - I believe simulation used to happen in the individual submission step, but we switched to using the already computed gas estimate from the IGP check in the `prepare` step, to save an RPC call - this results in senders being charged from their IGP allowance unnecessarily, and messages becoming undeliverable due to insufficient gas The correct flow requires three delivery simulations: 1. in the `prepare` step, to estimate gas and check the IGP policy 2. in the batch submission logic, to filter messages that are made invalid by earlier messages in the batch 3. right before submitting again, in case the batch caused the message to not be deliverable ### Solution Dry-run right before submitting an operation, and if it fails send it back to the prep queue		2 months ago
