What the contract can do
A token proxy created by the official bridge, owned by the bridge contract 0x4fD0aaa7506f3d9cB8274bdB946Ec42A1b8751Ef, which mints it when WBTC is locked on Ethereum and burns it on the way back. The address is the one the bridge itself returns for Ethereum’s WBTC (bridgedTokenAddress), and owner() of the token returns the bridge — both read on-chain at block 27,821,066 (2026-10-17 14:02 UTC).
Unlike the other bridged tokens listed here, PulseScan showed eWBTC as not verified on 2026-10-17, so its source cannot be read on the explorer.
Who controls it
The bridge is an upgradeable proxy controlled by single wallets, not multisigs. Its owner, 0x4792865c793a2Db4DEbDB30fCb8E38C45B09e7dF (last used to set fees on 10 March 2024), can change fees and limits and can also point the bridge at a different message contract — a power that bypasses the validators. Its upgrade owner, 0xF3BEC23E2f9F9a6ED63191e9dB5EAdDBF97555C9, can replace the contract code and has never done so. Transfers need 5 of 8 validator signatures, and the validator set itself is managed by separate single-key owners. Details on the bridge.
History
The bridge’s token-mediator contracts were deployed on 15 May 2023. Fees read on-chain for this token at block 27,821,066: 0.30 % from PulseChain to Ethereum, 0 % the other way, plus gas; daily limits also apply.
Risks
Everything that applies to bridged tokens applies here, plus the unverified source: the bridge’s single-key roles — owner, upgrade owner and the owners of the validator contracts — must not be misused or stolen, and fewer than 5 of the 8 validator keys may be compromised.
Unverified look-alikes with similar “… from Ethereum” names exist; use only the address above.
Verdict
Bridged asset, not on the trusted list: essential infrastructure, but upgradeable and controlled by single wallets, so it does not meet criterion C3.
Where to use it
Interfaces that call these contracts, checked on 2026-10-19 — official ones first. A listing is not an endorsement: open apps from a bookmark, check the domain before you connect a wallet and read the risk line. Domains to avoid and what to do when an app is down: Interfaces.
-
Official PulseChain bridge
bridge.pulsechain.com
OfficialPulseChainEthereum
Moves tokens between Ethereum and PulseChain, including the claim step on Ethereum. Its contracts are the only ones that mint and redeem eDAI, eUSDC, eUSDT, eWETH and eWBTC.
The same version also runs as an IPFS mirror and a self-host build.
Risk: 0.30 % fee from PulseChain to Ethereum; admin keys and validators are explained on the bridge page. HEX(eth) bridged to PulseChain becomes a different token, “HEX from Ethereum”.
-
PulseX app
app.pulsex.com
Official PulseX appPulseChain
Swaps, PLS ↔ WPLS wrapping, liquidity on PulseX v1, v2 and the eDAI/eUSDC/eUSDT stable pool, INC farms (deposit, withdraw, harvest, emergency withdraw) and the buy-and-burn page.
The same version also runs as an IPFS mirror and a self-host build.
Risk: Copycat PLSX and INC tokens exist — add tokens to your wallet by address only. The burn page’s conversion can be triggered only by whitelisted callers.
-
PulseScan — Read and Write contract
scan.pulsechain.com
Official PulseChain appPulseChain
Read contract, Write contract and Write proxy for every verified contract once you connect a wallet. It is the fallback when an app is down, and the only interface for some functions: the Maximus Mystery Box and escrow, MAXI’s own stake end, and the Hedron/Icosa liquidation auctions.
The same version also runs as an IPFS mirror and a self-host build.
Risk: Raw calls with no safety net: wrong units or a mistyped address cannot be undone. There is no Write tab for unverified contracts — eWBTC, “HEX from Ethereum”, the four Diamond Hands reward-distribution contracts and the ProveX escrow (verified on Sourcify only).
-
Piteas
app.piteas.io
Third partyPulseChain
DEX aggregator: routes swaps through PulseX and other exchanges via its own router.
Risk: The executor contract is not verified; the router’s owner — a single key — can pause it and change the executor. The fee is built into the quote (about 0.12 % on average, per its docs). Router audited by SolidProof (2023).
-
Gibs Finance
gibs.finance
Third partyPulseChainEthereum
Ethereum ↔ PulseChain transfers through the official bridge contracts plus its own helper routers, which can pay an optional delivery fee to whoever completes the claim. Its BNB Chain route uses the Tokens Express bridge.
Risk: The helper routers are owned by a single key, which can rescue stuck tokens and set a validator filter. The interface source is private (releases are signed and served from IPFS). The BNB Chain route carries the Tokens Express risks below. HEX(eth) bridged to PulseChain arrives as “HEX from Ethereum”, a different token.

Tokens Express
tokensex.link
Third partyPulseChainEthereum
Ethereum route: the official bridge contracts. BNB Chain route: a separate bridge.
Risk: BNB Chain route: a separate bridge whose PulseChain contracts and fee manager are owned — and can be upgraded — by one key, with a 2.97 % fee in each direction (read on-chain 2026-10-19). Tokens bridged from BNB Chain are not the e-tokens, and HEX(eth) bridged to PulseChain arrives as “HEX from Ethereum”. Closed source, delivered in a deliberately unreadable form.
Listing a token is not a recommendation to buy it. Read the trust criteria and the disclaimer.
