The complete record from The Coin Wire.

  1. How Much ETH Should a Treasury Keep for Token Swaps?

    A treasury’s ETH reserve should cover measured swap and approval gas under stressed conditions, with a separate buffer for timing, chain choice and operational delays.

  2. Bridge the right assets before joining a Polygon pool

    Before joining a Polygon pool, move the exact supported token to Polygon PoS, keep POL for gas, and confirm the pool’s network and token contract.

  3. Why Avalanche Pool Prices Can Mislead Smart Contracts

    A pool’s spot price describes its current balance, not a reliable market value; thin liquidity, trade size and oracle design can change what a contract should trust.

  4. A token swap estimate is a quote, not a promise

    A token swap estimate combines pool price, fees, route depth and slippage; checking those parts before signing shows what can change before on-chain settlement.

  5. Reading a BNB Chain Wallet’s Token History

    Search your wallet address in a block explorer, then read token transfers alongside the transactions that caused them to distinguish payments, swaps and approvals.

  6. SEC proposes conditional self-custody for crypto funds

    The SEC proposed allowing advisers and regulated funds to self-custody some crypto, with board oversight, key controls and annual accountant reports as checks.

  7. A Token Pause Can Stall One Leg of a Polygon Bridge Transfer

    A token pause can block one leg of a Polygon Bridge transfer without stopping the bridge itself; check the transaction state before retrying or seeking recovery.

  8. Utexo plans to bring USDT back to Bitcoin through RGB

    Tether-backed Utexo plans to issue USDT on Bitcoin via RGB this month, reviving the token’s original network while testing a more private payment model.

  9. Why a Wrapped Bridge Token May Not Redeem Yet

    A wrapped bridge token is redeemable only through the route and contract that issued it; delays, liquidity gaps and paused bridges explain many failures.

  10. A Swap Is Not Complete When the First Chain Says Success

    Tracking an omnichain swap links source confirmation to destination execution, showing route progress and why one transaction hash alone cannot prove delivery.

  11. BaseSwap on Base: swaps and liquidity carry different risks

    BaseSwap lets Base users swap tokens or supply liquidity; the choice turns on convenience versus pool risk, and on what providers need to track after depositing.

  12. SEC proposes conditional crypto self-custody for advisers and funds

    SEC proposal would let advisers and funds self-custody some crypto when no qualified custodian is available, with controls and board oversight.

  13. Is Chainflip Right for Your Cross-Chain Swap?

    Chainflip swaps native assets across chains without wrapped tokens, but the right route depends on custody, asset availability and how much coordination a swap requires.

  14. FCA opens crypto authorisation gateway ahead of 2027 rules

    The FCA opened crypto authorisation on 30 September, giving firms until February to seek approval before broader rules take effect in October 2027.
