Bridge risk associate with stablecoins

I’ve noticed that no Fantom native USDC or USDT is issued on by Circle or iFinex, so bridging is required for these stablecoins to exist on Fantom.
1. Why is this?
2. is Fantom working with Circle/iFinex to issue Fantom native USDC/USDT

USDT: currently available on 12 protocols and blockchains, including Ethereum, Tron, Solana, Omni, Avax, Tezos, Algo, EOS, Liquid, Statemint, SLP and Near
USDC: currently available on Ethereum, Hashgraph, Algorand, Avax, Solana, Stellar, Polygon, and Tron
