🤖AutoSniper

AutoSniper is a service consisting of both on and off-chain components that work together to snipe NFTs for oSnipe community members. Off-chain, oSnipe monitors marketplaces through a combination of APIs and chain event listeners. Whenever a new listing is detected, it runs through a series of filters to determine if that event is a match for an AutoSnipe. If it is, a transaction is assembled offline before submitting it to the AutoSniper contract.

The AutoSniper contract conducts a series of checks to ensure that the Snipe is allowed by the given sniper. Snipers can set an on-chain allowlist of NFT contracts, tip amounts, marketplaces, and more to prevent malicious action by the off-chain bot component. If all of these checks pass at the contract level, the purchase is forwarded to the appropriate marketplace, and the resulting NFT is transferred to the Sniper. All of this happens in a single atomic transaction, so you either win the snipe or nothing happens at all. There are no failed transactions, and no gas lost as a result of failed snipe attempts.
