💡 A Hardware $BTC Wallet Shouldn’t Ask You to Sign Something You Can’t Read On September 8, Trezor rolled out ERC-7730 Clear Signing across Safe 3, Safe 5, Safe 7 and Model T. The update tackles “blind signing” - a long-standing problem with smart-contract transactions. Here's how it worked earlier: you might think you’re approving a swap of 2,000 USDC for $ETH , while the hardware wallet itself shows something like: " 0xa9059cbb000000.... Approve? ✅ ❌ " There’s almost nothing useful for you to verify. With Clear Signing, the same transaction can be shown as: → Swap 2,000 USDC → Receive ETH → See the protocol / recipient → Approve So a hardware wallet is doing more than keeping the private key offline. It can also help you understand what that key is actually authorizing before the transaction becomes irreversible. ERC-7730 was originally developed by Ledger and is now supported by the Ethereum Foundation. It doesn’t cover every dApp yet, but the direction is interesting. 🏦 We hear a lot about regulation, tokenization and institutions moving onchain. But some smaller crypto upgrades like making sure people can actually understand what they’re clicking - are equally important. #BTC Price Analysis# #Macro Insights# #ETH
