What is DCA (dollar-cost averaging) onchain?

Dollar-cost averaging (DCA) is buying a fixed dollar amount of an asset on a regular schedule, say $50 of ETH every week, regardless of the price. Doing it "onchain" means the recurring buys run automatically through smart contracts and onchain swaps, instead of you placing each order by hand. The point is to remove timing and emotion from the decision: you buy more when prices are low and less when they're high, averaging your entry over time.

How onchain DCA works

• You set the parameters once: which asset, how much, how often, and for how long.
• An automation executes a swap (ex: stablecoin → ETH) on each scheduled interval.
• Each buy settles onchain to a wallet you control, so you can see and verify every transaction.

Because it's automated, you don't have to remember to place orders or watch the market: the schedule does it for you.

What to weigh

• Gas and swap fees: frequent small buys can rack up fees; on cheaper chains or L2s this matters less. Balance frequency against cost.
• It's a strategy, not a guarantee: DCA reduces timing risk but doesn't guarantee a profit, and it can underperform a single well-timed lump-sum in a steadily rising market.
• Custody: prefer automation where the recurring buys land in a wallet you control rather than a third party holding your funds.
