Redeploy wormhole wrapped Dai with 6 decimals #205
-
|
Currently, SPL USDC and USDT have 6 decimals. Dai has 18 decimals on Ethereum, and it must be shrunken down to 9 on Solana. Can we further just shrink the number of decimals down to 6? This makes it easier for dapps to integrate wormhole dai with the existing SPL USDC and USDT tokens. |

Wrapped tokens are deterministically generated by Wormhole: There's no way to redeploy them or dynamically adjust the decimals. Is the SPL ecosystem generally using 6 decimal tokens, or are USDC and USDT a special case? |

Yes. Serum, Raydium, Cope all only have 6 decimals: https://explorer.solana.com/address/4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R @leoluk, I think you guys should reconsider standardizing all wormhole tokens to 6 decimals. Having decimal mismatches creates unnecessary burden on Dapp developers and opens a wide surface area for bugs (especially decimal precision-related bugs). |

Yeah, that'd be the only option - have six decimals on all wrapped tokens. We'll consider it - thanks for bringing it up! |
