😫 Problem: Transactions are Unpredictable

  • Transactions can get dropped for seemingly no reason, costing you money and time
  • Transactions can be extremely slow from the time you send them to the time they get mined
  • Public transactions can fall victim to frontrunning and arbitrage
  • Users have to manually refresh their apps to know the status of their transactions

😃 Solution: Alchemy Transact

Alchemy Transact replaces opaque complexity with actionable clarity in the transaction life-cycle.

How it works

Transactions occur in 4 primary steps:
1. Create You decide to send a transaction at a specific gas price
2. Simulate You preview how your transaction will behave once it’s sent
3. Send You send your transaction to get executed on chain
4. Monitor You follow along to ensure your transaction is successful

At each step, Alchemy Transact can help optimize the transaction to increase its chances of going through quickly, reliably, safely and affordably:



1. Reinforced Transactions

The Reinforced Transactions engine automatically tracks and re-sends your transactions if they are not going through, so you don't have to worry about your transactions getting dropped (especially during network congestion).

2. Private Transactions

The Private Transactions endpoints are a way to send and cancel transactions without exposing them to the public mempool, preventing unwanted arbitrage and front running.

3. Notify

Alchemy Notify offers a key benefit within the transaction lifecycle, giving you real-time alerts when transactions are mined or dropped from the mempool. This allows you to notify your users when transactions are final instead, so they don’t have to refresh the screen to see if the transaction was confirmed.
