OpenSea on Solana: Aggregated NFT Trading

OpenSea runs a native Solana marketplace. Chadbot now reads that order book straight from the chain and merges it with Tensor and Magic Eden — and it prices differently from both, in a way that matters to anyone buying.

All guides
Quick answer
OpenSea's Solana marketplace is now aggregated inside Chadbot, alongside Tensor and Magic Eden. Its listings and collection bids join the same price ladder, bid book and depth chart; its sales feed the live screener and the volume analytics. Everything is read from the blockchain itself — no marketplace API sits in the path. And its economics are inverted: the buyer pays exactly the ask, because the 1% fee and the royalty come out of the seller's side.

OpenSea1.0000

Same NFT, same ask — about 7% cheaper to buy.

OpenSea is the mirror image of Tensor: the maker bears the fee and the royalty, so the taker pays exactly the ask.
// Key takeaways
  • The buyer pays the ask, full stop — no marketplace fee and no royalty added on top.
  • The seller pays 1% + royalty — the mirror image of Tensor and Magic Eden, where the buyer is charged instead.
  • At the same headline ask, buying here costs ~6.5% less on a 5%-royalty collection.
  • Read entirely from chain — no API key, no rate limit, no marketplace uptime in the path.
  • USDC-priced and expired orders are kept out of the SOL book rather than quietly mixed in.
  • Bid bots, listing bots and the sniper all run on it — and repricing happens in place.

OpenSea has a Solana marketplace

OpenSea runs a native Solana program that holds its own listings and collection bids on-chain — a genuinely separate venue with its own liquidity, not a bridge or a mirror of another chain's book.

Chadbot reads that program directly. Its orders are decoded from the marketplace's own accounts, and its sales from the events the program emits when a trade settles — so a price shown here is the price the chain recorded, not a number an API reported.

The fee flips sides — and that is the whole point

This is the single most useful thing to know about the venue. Every Solana marketplace charges roughly the same amount; they disagree about who pays it.

  • Tensor — the buyer pays the ask plus 2% plus the creator royalty. The seller receives the full ask.
  • OpenSea (Solana) — the buyer pays exactly the ask. The seller receives the ask minus 1% minus the royalty.

So the same 1.0000 ◎ ask is a different trade depending on where it sits. Comparing headline asks across venues quietly favours whichever one hides its costs on the buy side — which is why Chadbot compares all-in taker cost instead.

Pro tip
A resale has to clear fee + royalty to break even here, because both come out of your proceeds. Listing back at the price you paid is a loss, not a wash — the same trap as cross-listing between any buyer-pays and seller-pays venue.

Running bots on it

The automation works the same way it does everywhere else in Chadbot, with one advantage that is specific to this program.

  • Collection-bid bots keep a live, competitive offer on a collection and re-price it for you — see how auto-bidding works.
  • Listing bots list, re-price and delist for you, and can move an NFT between OpenSea, Tensor, Magic Eden and Orbis — cross-marketplace relisting.
  • The sniper auto-buys listings the moment they hit your price, with a spend ceiling the program itself enforces.

Repricing keeps your place in the queue

On most venues changing your bid means cancelling it and making a new one — two steps, and your order goes to the back of the queue at the new price. Here a re-price rewrites the existing order in place and settles the difference either way: raising it tops the escrow up, lowering it refunds you. One signature, and the order never loses its position to someone racing you.

Listings work the same way: a re-price edits the order rather than replacing it, and it moves no rent at all — so adjusting your price costs nothing but the network fee.

What this venue does not do

Two bot types have nothing to run against here, and that is a property of the marketplace rather than a gap in Chadbot:

  • No AMM pools. The program is a pure order book — there is no pool primitive to quote a curve against, so AMM bots stay on Tensor.
  • No trait bids. The program has no attribute targeting at all, so trait bidding runs on Magic Eden and Tensor instead.

There is also no shared escrow wallet to pre-fund: a bid holds its own SOL on-chain, and cancelling returns it to you in full.

Grey is the headline ask; bold is the taker cost. On Tensor and Magic Eden the buyer adds the fee and the royalty on top — on OpenSea and Orbis they do not.

OpenSea's asks merge into the same ladder as every other venue. Sort by what you actually pay and the order changes — an OpenSea ask adds nothing on top, so it can beat a lower headline elsewhere.
  • Collection pages — OpenSea listings in the price ladder, its collection bids in the bid book and the depth chart.
  • The live feed — new listings, re-prices and fills as they land on-chain.
  • Volume and analytics — OpenSea joins the 24h marketplace breakdown and the volume charts.
  • Wallet activity — OpenSea trades carry the OpenSea mark, and filter like any other venue.

FAQ

Does OpenSea have its own marketplace on Solana?

Yes. OpenSea runs a native Solana marketplace program, separate from the Ethereum contracts most people associate with the brand. It holds its own listings and collection bids on-chain, and Chadbot reads that order book directly and folds it in beside Tensor and Magic Eden.

Why is buying on OpenSea's Solana marketplace cheaper at the same price?

Because the fee lands on the other side of the trade. On Tensor the buyer pays the ask plus a 2% marketplace fee plus the creator royalty. On OpenSea's Solana marketplace the buyer pays the ask — the 1% fee and the royalty come out of the seller's proceeds instead. At the same headline ask on a 5% royalty collection, buying there costs about 6.5% less. The one addition is on older SPL NFTs, where the buyer also funds the token account that receives it (roughly 0.0019 SOL); newer Core and compressed assets have no such cost.

So is selling there worse?

It's the mirror image, and it depends which side you're on. On Tensor and Magic Eden the marketplace fee is charged to the buyer, so a seller there receives the full ask. On OpenSea's Solana marketplace the seller receives the ask minus 1% minus the creator royalty. Neither is simply better — the same trade costs the buyer less and the seller more. What it does mean is that a break-even resale has to be priced above your cost by fee plus royalty, which is what Chadbot's listing bots do for you automatically.

Does Chadbot use OpenSea's API for this?

No. Every listing, bid, sale and price comes from the Solana blockchain itself — the marketplace's own accounts and its on-chain events. Nothing depends on an API key, a rate limit or a marketplace's uptime.

Are USDC-priced OpenSea listings included?

They're read, but they're kept out of the SOL order book and out of SOL volume. A USDC amount is not lamports, and mixing the two would put a wrong number on the page rather than a wrong label — so non-SOL orders are excluded from anything denominated in SOL.

Do expired listings show up as buyable?

No. An OpenSea listing can carry an expiry, and buying an expired one fails on-chain. Chadbot filters expired orders out of the book before anything is called a floor or a best ask.
