Yellow wallet

What is Yellow (YELLOW)?

Most of what Yellow does never touches the Ethereum chain, and that is the whole idea. Yellow Network is a clearing layer built on state channels: two parties open a channel with an on-chain deposit, then exchange co-signed balance updates off-chain as fast as they can sign them, and only the final state is settled back to Ethereum. If one side stops cooperating, the last co-signed state can be enforced through the on-chain contracts. The Nitrolite protocol defines these channels, and clearnodes sit inside them, routing liquidity between brokers, applications and liquidity providers across the chains the network reaches, while the Yellow SDK lets developers plug in without running channel infrastructure themselves.

YELLOW itself is the ordinary part of the picture. It is an ERC-20 token on Ethereum with no rebase and no built-in accrual: the balance in your wallet is exactly the number of tokens you hold. Inside the network it works as collateral and as the unit clearing fees are counted in - operators who want to run a clearnode lock YELLOW to take part. None of that changes anything on the holder's side. Every transfer is a normal Ethereum transaction paid for in ETH, so an address holding YELLOW and zero ETH cannot move the tokens until some ETH arrives.

One thing to check before adding the token: "Yellow" is a crowded name. Yellow Duckies (DUCKIES), which grew out of the same ecosystem, is a separate token with its own contract and is not YELLOW, and various unrelated tokens reuse the word. The genuine asset on Ethereum is the project's own ERC-20 contract; confirm it through the project's official channels rather than taking the first match in a token list.

In Tangem the token sits beside ETH in the same wallet, so the gas coin is already where the transaction needs it, and the transfer is signed by tapping the card to the phone, no cable and nothing to charge. Keeping YELLOW and its ETH together and signing that way turns the occasional transfer into the same two steps every time, which is all this token really asks of a wallet.
