Sei · Chain ID 1329 · SEI
Sei NFT verification and token-gated Discord roles.
Give Sei holders their Discord roles without asking anyone to connect a wallet. NXT reads Sei directly over RPC, checks NFTs, traits, token balances, and staking contracts, and keeps roles in step as tokens move.

What works on Sei. Every rule type, plus the bots.
NFT rules
Contract, Token IDs, Quantity, and Trait rules read Sei contracts directly. ERC-721 and ERC-1155 are both supported, with token IDs for ERC-1155, and trait rules read ERC-721 metadata from tokenURI.
Token and coin balances
ERC-20 rules gate on any fungible token deployed on Sei, with a minimum and optional maximum. Native balance rules require a minimum SEI balance, summed across a member's wallets.
Staking, Combo, Custom API
Count tokens held in a Sei staking contract, combine up to five conditions across Sei and other chains, or let your own HTTPS endpoint decide eligibility.
OpenSea collection rules
OpenSea covers Sei, so you can reference a collection by its slug and NXT counts holdings across its contracts. The floor bot can report floor price, owners, and 24 hour volume for Sei collections.
Sales bot
Sales paid in SEI are detected from on-chain transfers and posted with the token image, price, buyer, seller, an OpenSea link, and a seiscan.io transaction link. Sales paid in a wrapped token or a stablecoin are not detected on Sei.
Art bot and real-time checks
Show any Sei token with its image and traits on request. NFT transfers on gated Sei contracts trigger a re-check of the sender and receiver within seconds, on every plan.
How Sei holders verify. No wallet connect.
Members never connect a wallet or sign a message. To prove a wallet, a member clicks Verify in your channel, enters an address, and sends a tiny, unique amount from that wallet back to the same wallet. On Sei, that means a self-transfer of a fraction of SEI: the coin returns to the sender, so the only cost is the network fee in SEI.
The member can paste the transaction hash from seiscan.io, or leave it blank and NXT searches recent blocks for the transfer. Members do not have to prove on Sei specifically: any listed network works, so someone holding Sei NFTs can prove the same address on whichever network they have gas on, because an EVM address is the same on every chain. Where the server enables it, an OpenSea profile bio code is a second option.
A wallet proven once works in every NXT server. Holders who keep Sei tokens in a cold wallet can import it through a delegate.xyz v2 full-wallet delegation registered on Ethereum, Base, Arbitrum, Optimism, Polygon, or ApeChain. Once linked, the cold wallet's Sei holdings count toward your rules.
Gate a role on Sei. Three steps.
Add NXT and pick the role
Add NXT to your server and move its role above the holder roles it will manage. In Dashboard > Token gated roles, click Add role and choose a rule type.
Select Sei
Choose Sei as the network and paste the contract address, which you can copy from seiscan.io. NXT reads the contract and, for ERC-20 tokens, fills in the symbol and decimals.
Post the verify panel
Post the verify panel in a channel members can see. Members click Verify once, and NXT re-checks them every 2 days on Free, daily on Growth, and hourly on Pro, plus on every NFT transfer.
Sei RPC. Public by default, yours if you want.
Sei works out of the box on NXT's public RPC endpoints with automatic failover between them. If an endpoint fails or times out, NXT moves to the next one, and if every endpoint fails the result is unknown, which never removes a role.
If your project has its own Sei endpoint, for example a paid plan with higher limits, add it in Dashboard > Networks with chain ID 1329. It is used only for your server's checks, proofs, and tests, NXT's public endpoints stay behind it as a fallback, and the dashboard shows only the host so an API key in the URL stays hidden. Removing it switches your server back to the public endpoints without touching your rules.
