OpenSea Bidding Bot — Collection, Trait & Token Offers on Autopilot

Ethernyx automates the entire OpenSea offer game: collection offers, trait offers and per-token bidding at up to 300+ bids per second — with instant counter-bidding when you're outbid and automatic cancellation of stale offers. Cloud-based, nothing to install.

All three offer types

Collection, trait and single-token offers — including token bidding across thousands of NFTs with individual prices.

Up to 300+ bids/sec

Reprice an entire portfolio of offers within a market tick. Speed tiers from 5 to 300+ bids per second.

Instant counter-bidding

Websocket-driven reaction: the moment a higher offer lands, yours goes back on top — within your max price.

Auto-cancel on outbid

Offers that stop making sense get cancelled automatically. No stale bids buying tokens at yesterday’s price.

Smart pricing rules

Bid relative to floor or top offer, set min/max bounds, undercut controls and offer lifetimes per task.

Runs 24/7 in the cloud

No desktop app, no VPS. Configure tasks in the browser; they keep bidding while you sleep.

Common questions

Do OpenSea offers cost gas?

No — WETH offers are off-chain signatures, so placing and repricing thousands of offers is free. Gas applies mainly when sellers accept.

What is token bidding?

Individual offers on individual tokens, each with its own price — the highest-precision strategy on OpenSea. We explain the meta in NFT Bidding in 2026.

Can I try it before paying?

Yes — the free tier lets you run the full flow end-to-end. Paid tiers raise speed and task limits.

Does it also work on Blur?

Yes, Ethernyx runs both marketplaces side by side — see the Blur bidding bot page.
