Terra vs Near
Popular protocols from Etherium to near: makeDao
coingecko.com, popular markets (биржи): binance, huobi global, OKEx
- polygon is compatible with Etherium (2d level blockchain)
- Aurora is like polygon
Aurora protocols: 1inch, dodo, chainlink, near protocol
Validator app - you give them NEAR coin -> they stake it
NEP 141 -- ???
- inflateable token -
- stable tokens -
nearpad will use Aurora
1 ehter = 10^9 gwei = 10^18 wei
dappradar.com, awesomenear.com
- Rainbow Bridge - swap eth to near
connect: metamask (can add any RPC remote proc coll network) or NearWallet (wallet-connect compatible - QR to allow from mobile with metamask to browser exchange)
The following popular tokens with common ERC-20 functionality will now be able to interoperate with NEAR, including but not limited to:
Стейблкоины USDT (Tether), DAI, TUSD
Обёрнутые токены WBTC и WETH
Токены децентрализованных бирж 1INCH и UNI
Токены кредитования AAVE и COMP
Служебные токены HT (Huobi) и CRO (Crypto.com)
allows any information that is cryptographically provable on NEAR to be usable in Ethereum contracts and vice versa — including the ability to read the state and schedule calls with callbacks on the other chain.
This means a user can vote with their ETH balance in a NEAR DAO without sending a transaction on Ethereum
