The Blockchain Integration Trilemma

Everyone in crypto knows the classic blockchain trilemma: speed, security, decentralization. You can optimize two, never all three.

After spending 5 years leading blockchain integrations at Ledger, and then discussing integration strategies with 100+ crypto companies as CEO of Adamik, I'm convinced there's another trilemma that matters just as much, and it quietly shapes the success or failure of many multi-chain roadmaps.

The Blockchain Integration Trilemma (for Businesses)

If you're a VP Product or Head of Blockchain building a product where chain support is a key differentiator, you will eventually be forced into a trade-off between:

• Time-to-market: Ship fast. Add chains and features quickly. Keep momentum.

• Sovereignty: Control architecture and reliability: vendor dependencies, observability, internal compliance posture, and most importantly, security at signing time (what your system or user is actually approving).

• Scope: Support many chains with deep functionality: balances, history, tokens, staking, complex transactions, simulation, swaps, bridges.

You can optimize two. Not all three.

Why This Trilemma Exists

Because "integrating a blockchain" is not a one-off deliverable.

The hard part isn't adding one chain. It's operating multi-chain over time, when reality kicks in:

• Protocol upgrades that break assumptions

• Edge cases that only appear at scale

• Fundamentally different models (account vs UTXO, fee, finality behaviors, token standard(s) and staking)

• Provider instability and uneven infrastructure quality across ecosystems

• Monitoring, testing, incident response. Multiplied by N chains

• The hidden tax: every integration becomes a long-term maintenance contract

At Ledger, we learned this the hard way. The first integrations feel finite. Then you hit a threshold where your roadmap becomes less about product and more about maintaining plumbing.

The Most Common Failure Mode

In almost every company, someone eventually asks the CTO or Engineering Manager: "Can we build this internally?"

The honest answer is almost always yes. Given enough time and enough people, everything can be built.

But it's usually the wrong question. The right question is:

What matters most for our business right now, at our current stage?

The answer changes depending on whether you're proving product-market fit, scaling distribution, moving into enterprise constraints, or defending a competitive moat.

"Can we?" is an engineering question. "Should we now?" is a business question.

Build vs Buy Is About Opportunity Cost

Over the past years, I've seen teams over-index on "owning everything" early and pay for it with delayed launches, brittle integrations, and a permanent tax on hiring and maintaining long-tail chain expertise.

I've also seen teams favor speed and end up locked into a provider, with limited flexibility, and unpleasant surprises when reliability doesn't match production needs.

This is why I like framing Build vs Buy as a conscious way to pick your position in the triangle. Not as a philosophical debate.

We summarized the trade-offs here (time, maintenance, scope, and security implications).

Practical Takeaway

Before announcing "we'll support 30 chains this year," align on two things:

1. Which two corners of the triangle are we optimizing for right now?

2. How do we rank chains and decide what's internal vs outsourced? There is no one-size-fits-all—and the uncomfortable truth is that even on some high-volume chains, reliable services can still be scarce.

The teams that execute well on multi-chain aren't the ones with the most engineers. They're the ones who made the trade-off explicit before committing.
