Optimism · Chain ID 10 · ETH
Optimism NFT verification and token-gated Discord roles.
NXT turns what members hold on Optimism into Discord roles. Gate channels on a collection, a trait, an ERC-20 balance, or a minimum ETH balance, and let members prove a wallet with a same-wallet transfer instead of a wallet connection. On Optimism, gas for a self-transfer is paid in ETH and is typically small, which makes it a convenient network for members to prove a wallet even when their holdings sit on another chain.

What works on Optimism. Every rule type, plus the bots.
NFT rules
Contract, Token IDs, Quantity, and Trait rules read Optimism 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 Optimism, with a minimum and optional maximum. Native balance rules require a minimum ETH balance, summed across a member's wallets.
Staking, Combo, Custom API
Count tokens held in a Optimism staking contract, combine up to five conditions across Optimism and other chains, or let your own HTTPS endpoint decide eligibility.
OpenSea collection rules
OpenSea covers Optimism, 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 Optimism collections.
Sales bot
Sales paid in ETH and in WETH are detected from on-chain transfers and posted with the token image, price, buyer, seller, an OpenSea link, and a optimistic.etherscan.io transaction link.
Art bot and real-time checks
Show any Optimism token with its image and traits on request. NFT transfers on gated Optimism contracts trigger a re-check of the sender and receiver within seconds, on every plan.
How Optimism 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 Optimism, that means a self-transfer of a fraction of ETH: the coin returns to the sender, so the only cost is the network fee, paid in ETH on Optimism.
The member can paste the transaction hash from optimistic.etherscan.io, or leave it blank and NXT searches recent blocks for the transfer. Members do not have to prove on Optimism specifically: any listed network works, so someone holding Optimism 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 tokens in a cold wallet can delegate the full wallet on delegate.xyz (v2) to a hot wallet, and NXT reads those delegations on Optimism, so the cold wallet never has to sign or send anything.
Gate a role on Optimism. 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 Optimism
Choose Optimism as the network and paste the contract address, which you can copy from optimistic.etherscan.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.
Optimism RPC. Public by default, yours if you want.
Optimism 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 Optimism endpoint, for example a paid plan with higher limits, add it in Dashboard > Networks with chain ID 10. 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.
