The Crypto Swap Reseller Problem

The Scheme

NEAR Intents is a cross-chain swap protocol. It aggregates liquidity from competing market makers and executes swaps across 20+ blockchains. The protocol is free — zero fees for registered partners. The API is publicly documented at docs.near-intents.org.

Swap.my and EagleSwap are frontends built on this free API. They present themselves as independent exchanges. They are not. They take the NEAR Intents rate, silently add a markup, and pocket the difference. They don't disclose the underlying provider. They don't show the pre-markup rate. The fee isn't listed as a "fee" — it's hidden inside the exchange rate.

Every transaction is recorded on the NEAR blockchain with the fee amount and recipient baked into the appFees field. We pulled it all. Here's what we found.

Swap.my (swap.my)

Successful Swaps

Hidden Fee (72 bps)

On-Chain Fee Recipient

appFees: [{
  "recipient": "swapmybuddy.near",
  "fee": 72
}]

Every Swap.my transaction contains this fee entry. 72 basis points (0.72%) — more than double EagleSwap's markup. The NEAR account name swapmybuddy.near makes attribution unambiguous.

Quote Discrepancy

In our testing, Swap.my quoted a user 0.748856 USDT for a 0.01 SOL swap. The NEAR Intents Explorer shows the solver actually filled 0.749848 USDT. The difference is small on a $0.78 swap — but on a $10,000 swap at 72 bps, the user loses $72 to an invisible fee they never agreed to.

EagleSwap (eagleswap.to)

On-Chain Fee Recipient

appFees: [{
  "recipient": "Gcj5A3a5mF2BEPm4LujddTit7tTR8pNmUKXkcuzM4dC1",
  "fee": 30
}]

Every EagleSwap transaction on the NEAR blockchain contains this fee entry. 30 basis points (0.30%) routed to a Solana address they control. Verify any transaction at explorer.near-intents.org.

Security Issues

EagleSwap exposes an unauthenticated API at /api/swap/{id} that leaks:

Full NEAR Intents quote responses including solver signatures
User wallet addresses (both recipient and refund)
Deposit addresses and correlation IDs
Recent swap feed at /api/swaps — no authentication required

Any user's swap can be looked up by anyone who knows the order ID. This is how we identified their fee structure without any privileged access.

Unique Users Affected

Every dollar above was charged for adding a frontend to a free API. The users received no additional value — the same swap, the same speed, the same liquidity. Just a worse rate.

How We Found This

No hacking. No private data. No insider access. Just public blockchain records.

Identified the protocol: Both services use nep141: asset IDs, ed25519 signatures, and deposit addresses that resolve on NEAR — all signatures of the NEAR Intents 1Click API.
Found the fee wallets: EagleSwap's API is unauthenticated — their /api/swaps endpoint returns recent swaps with correlation IDs. We matched those to the NEAR Intents Explorer, which shows the appFees field on every transaction.
Pulled the full history: The NEAR Intents Explorer API supports filtering by affiliate — the fee recipient address. One query returns every swap that paid fees to that address, with full TX hashes on both the source and destination chains.
Verified independently: Every transaction hash in this report is clickable and verifiable on the respective blockchain's explorer. The origin chain TX shows the user's deposit. The destination chain TX shows what they received. The NEAR TX shows the fee that was extracted.

Reproduce It Yourself

# Search the NEAR Intents Explorer for EagleSwap's fee wallet
curl -H "Authorization: Bearer YOUR_JWT" \
  "https://explorer.near-intents.org/api/v0/transactions-pages?\
affiliate=Gcj5A3a5mF2BEPm4LujddTit7tTR8pNmUKXkcuzM4dC1&perPage=10"

# Search for Swap.my's fee wallet
curl -H "Authorization: Bearer YOUR_JWT" \
  "https://explorer.near-intents.org/api/v0/transactions-pages?\
affiliate=swapmybuddy.near&perPage=10"

# Get an Explorer API key at: partners.near-intents.org

Returns full transaction details: TX hashes, sender/recipient wallets, amounts, fees, timestamps. All public data.

Raw Data

Every transaction referenced in this report is included in our repository as raw JSON:

eagleswap_transactions.json — 1,111 EagleSwap transactions
swapmy_transactions.json — 5,152 Swap.my transactions

The Point

We're not saying Swap.my and EagleSwap are scams. They provide a service — a frontend for a swap protocol. Charging for that is a legitimate business model.

The problem is transparency. Neither service tells you:

That they're reselling NEAR Intents
What fee they're charging
That the same swap costs less (or nothing) elsewhere

uSwap Zero exists to prove that a swap frontend can be free, open source, privacy-first, and fully transparent — while using the exact same infrastructure. You shouldn't have to pay a hidden 0.30–0.72% tax to swap crypto. And you shouldn't have to trust us when we say that. Read the code.
