In 2017, EIP-140 introduced REVERT: failed contract calls could roll back state without consuming all remaining gas.
A reverted trade may leave token balances unchanged and still cost a transaction fee.
Disconnecting your wallet doesn't revoke token approvals.
An ERC-20 spending allowance can remain after your swap is done.
Check the spender and limit before approving; revoke permissions you no longer need onchain.
Ethereum postponed the Oct 26 Glamsterdam activation on the Hoodi testnet to investigate how proposed state creation gas changes interact with existing contracts.
For DeFi, compatibility testing matters more than rushing a throughput headline.
Galaxy Research modeled a 500-stock AMM at ~3% below simply holding the basket. At a 0.05% swap fee, it would need ~45x annual turnover just to break even.
A route with more hops can quote more tokens out and still be the worse trade. Each extra step may add gas.
For a swap, compare the net outcome after execution costs, not just the gross quote. More paths don't automatically mean a better fill.
Slippage tolerance doesn't undo price impact.
Price impact is already reflected in the quote for your trade size and available liquidity.
Slippage tolerance sets how much worse execution can get before the transaction reverts. Check the quote first, then the tolerance.
March 2023 is a reminder: a 'stablecoin pool' isn't necessarily stable under stress.
As USDC lost its dollar peg, trading flows shifted and pools became imbalanced. For LPs, the mix of tokens left in the pool can matter as much as fee income.
A fixed swap fee treats a calm market and a fast-moving one the same.
But LPs can lose value when arbitrageurs trade against stale pool prices. Higher or adaptive fees may help cover that risk, at a cost to swappers.
A 16-day Ethereum block study found swaps in the first 10% of block gas paid 8–17x the priority fees of those in the 30–60% band.
It's a measured association, not proof that bidding more guarantees earlier execution.
DefiLlama's snapshot showed a split in weekly DEX volume:
Ethereum ~-16%, Solana ~+7%.
A market-wide headline can hide very different trading conditions. Even chain volume won't tell you the depth of the pool you're about to trade.
A pool can have plenty of capital overall but little liquidity near the current price.
That's when a larger swap can move the price fast.
Ethereum researchers are exploring transaction assertions: checks that could revert a transaction if its final outcome breaks set rules.
For swaps, the focus is what happened, not just what got signed.
A tight LP range can earn fees efficiently while the market trades inside it. If price moves outside the range, that position stops earning swap fees until price returns or the LP repositions.
A quote reflects the pool state when it was calculated.
By execution, price and available liquidity may have moved.
For volatile pairs, check minimum received before signing.
DEX volume is down 20.2% week over week on DefiLlama's dashboard.
A quieter week can reflect volatility, trade sizes, or fewer trades. One chart can't tell you whether swaps got easier or harder to execute.
Before you buy a random token, a quick checklist can save you.
· Look at the liquidity: a thin pool means you might not be able to sell without crashing the price.
· Check how concentrated the holders are, since a few wallets holding most of the supply can dump on you.
· See if the contract is verified and audited, and whether the team is known.
And be wary of tokens you can buy but mysteriously can't sell. A few minutes of checking beats a painful lesson.
A perp lets you bet on a price going up or down with leverage, and unlike a normal futures contract, it never expires.
To keep its price tied to the real asset, perps use a funding rate, a small payment longs and shorts pay each other periodically. Leverage cuts both ways. It magnifies gains and losses, and if the market moves against you far enough, your position gets liquidated.
