Crosschain Swaps are live!
Today, we are introducing the Across Swap API for crosschain swaps in a single call.
Bridge and Swap are now one action.

Okay, would love some economists to help me here (cc @BlkBoxEconomist).
I assume GDP is generally measured in real terms (i.e. adjusted by inflation), so if AI makes many things cheaper (productivity improvement), then we would expect either more quality or quantity of those things to be consumed or for the extra surplus to be used elsewhere to increase production there.
Let’s use software as an example.
Software gets cheaper to make for a given level of quality and function. This means I get more, better software at the same cost OR the same software at a lower cost. This is deflation (see TVs over the last 20 yrs).
If the economy buys the same software for less money, then the real GDP of the software industry stays the same, but there is surplus to go elsewhere. GDP goes up.
If the economy buys more/better software for the same money, the inflation adjusted value has gone up because of the deflation. So GDP of the software industry has gone up. GDP goes up.
The only scenario where the productivity gains are not leaked from GDP is if the sane software is purchased for less money, the surplus goes elsewhere, and that surplus is used to chase supply constrained goods (land would be an extreme example) where each marginal dollar of spending produces less marginal value than the last.
Is this analysis right? What am I missing? @dwarkesh_sp and others seem quite convinced that the cheapness of the tokens (productivity gains) will work against extreme GDP growth.
Replying to @tszzl
What if cancer cures and life extension cocktails were $20 a pop? I don't see how that would necessarily lead to some huge downstream explosion in GDP, despite the fact that astronomical consumer surplus is created.
I agree GDP will grow. But potentially by much less that how different the world has qualitatively gotten.

Story routes disputes through @UMAprotocol to resolve conflicts using open, permissionless arbitration.
Proof-based claims instead of power-based outcomes.
Your IP, your rules.
AI is going the way of wikipedia. Everybody says it's unreliable until it isn't.
Our research team is pushing the boundaries of how reliable and accurate AI systems can be.
Soon, UMA will be able to provide faster, more objective, and (incredibly) cheap truth.
The UMA Optimistic Oracle has shown us how humans reach consensus.
How we collaborate, dispute, and converge on truth.
Now it's time to test what happens when AI proposes the answers.
Follow the experiment → @OOTruthBot

The Across Prime whitepaper is now live.
Across Prime introduces a bonded bridging model that improves capital efficiency.
Read more in this post from @danrobinson - @paradigm
Across Prime embraces the idea that a user can rely on their own view of the blockchain to prevent overallocation of relayer bonds.
While I was initially skeptical that this would be practical @danrobinson came up with a clever hash-matching mechanism to make this possible.
The mechanism is fairly simple, but has subtle advantages beyond capital efficiency:
- users can determine their own confirmation finality risk
- no settlement or messaging is required in the happy path
- unhappy path messaging can be slow or expensive without impacting users
It was a lot of fun to work with @danrobinson @hal2001 and the rest of the @AcrossProtocol team on this.
Full whitepaper here: paradigm.xyz/2025/05/across-…
