Asking the crypto community to help Colombia
On 10 August 2026 a magnitude 7.4 earthquake struck Colombia. Donate in USDC or USDT across five networks; ReFi Colombia receives the funds and decides how they reach affected communities. Every contribution has a public transaction, so the total below can be verified from the chain rather than taken from a number we control.

Who is behind this
I was born in Cali and have lived here all my life, one of the cities most affected by the 7.4 magnitude earthquake that struck Colombia on August 10.
At the time of writing this, public reports speak of 239 people killed, 3,755 injured, and 140 collapsed structures across the country.
These figures come from public reporting during an evolving emergency and may change. Last updated · Sources: El Colombiano, Infobae, CNN en Español, El Tiempo, La FM, Wikipedia.
I had been following with sadness, from a distance, what happened in Venezuela in recent weeks, but this time it was different because I had to live through it firsthand.

I wrote about what that day was like, and what happened to my apartment →
I had never felt so much fear: fear of losing my life and fear that my loved ones might no longer be there. Everything happened in less than two minutes, but to me it felt like much longer.
It is hard to describe how every movement increased the sense of hopelessness, and then how the collapse of communications made the anxiety even worse, not knowing how my family was doing.
I was fortunate that my loved ones are still alive and that we only suffered material damage, but this is not the reality for many people in my country.
There are still many people missing beneath the rubble, many family members desperate for answers, people who from one day to the next were left without a home, and many other situations that arise when a tragedy like this happens.
That is why I want to turn to the community that, over the last few years, has meant so much in my life — a community where I have grown, learned, shared knowledge, and dedicated so many hours of my life. A community I have always identified with because of its values and what it seeks to contribute to humanity.
That is why I decided to build an onchain donation channel so that anyone who wants to contribute to this cause can do so. For this, I joined forces with ReFi Colombia, a node of ReFi DAO, a decentralized community focused on the regeneration of the planet, so they can distribute all these donations among foundations, organizations, and the people who need them most. They have already moved more than COP $20 million — around US$5,000 — in stablecoins onchain across the country: weekly payments to more than 60 low-income families, and grants that funded mangrove restoration in Cartagena and reforestation in the Amazon.
If the crypto community has contributed to your life, this is the moment for you to do the same for a cause that is truly worth it.
Verify it yourself
You do not have to trust the totals shown by this site. The donation wallet and every movement in and out of it are public.
Donation wallet
0xf7d7a865342a7f20d55a1151d9aff31312fd06c1
This wallet belongs to ReFi Colombia. Payments do not land in it directly: Voulti processes them and credits the amount to ReFi Colombia inside its settlement contract, and ReFi Colombia withdraws from there to this wallet whenever they choose, without needing anyone's approval. Each withdrawal appears in the movements below.
Movements of the published wallet
Read straight from the blockchain, not from a number we typed in. Donations are paid into Voulti’s settlement contract first, so they appear here when ReFi Colombia withdraws them into this wallet.

What has been handed out
Where the money went after it left ReFi Colombia's wallet. Stablecoin payments carry their transaction, so you can check them yourself. Anything paid in pesos or spent offchain is reported by ReFi Colombia with whatever evidence exists — a claim with documents behind it, which is not the same thing as a proof, and this page will not pretend otherwise.

Questions
Why donate onchain?
With a traditional donation account, the public usually has to trust the total reported by the organiser. Here, anyone can independently verify the donations that arrived, the amount received and the movements between the published wallets.
The blockchain does not prove what happens after funds are converted or spent offchain. That is why ReFi Colombia's public reporting is the other half of the transparency model.
How your contribution moves
You donate from your wallet
Send USDC or USDT using one of the supported networks.
The donation becomes publicly verifiable
Once settled, the amount and transaction hash appear in the public donation ledger.
ReFi Colombia manages the funds
ReFi Colombia controls the donation wallets and decides how funds are distributed to affected communities.
Their use is reported publicly
Onchain movements remain visible here. ReFi Colombia will publish public updates about how resources are used after they leave the onchain wallet.
What ReFi Colombia has done before
ReFi Colombia has distributed more than COP $20 million — around US$5,000 — in stablecoins, directly onchain, to projects across Colombia. That includes a national subsidy programme paying more than 60 low-income families every week on Celo, mini-grants that funded mangrove restoration in Cartagena and native-species reforestation in the Colombian Amazon with ReFi Cartagena and ReFi Amazonas, and community programmes that brought hundreds of Colombians onchain for the first time, with 145 POAPs minted across their events.

These are their own records, published by them. Nothing here asks you to take our word for it.
The money
- Who receives the money, and who decides how it is used?
- ReFi Colombia, on both counts. They control the wallet, decide the disbursements, coordinate with the organisations and people who need support, and publish updates through their own channels. DonaOnchain never holds the money and cannot decide how it is spent. We are deliberately not publishing fixed percentages in advance: needs change hour to hour in an emergency, and a split we could not enforce would be a promise made on ReFi Colombia’s behalf.
- Is there a moment when someone else could move it?
- Yes, and it is short. Between your payment and ReFi Colombia’s withdrawal the funds sit in the settlement contract of Voulti, the payment processor, which can technically move them during that window. ReFi Colombia withdraws on their own, without needing anyone’s approval. This page shows you both steps rather than claiming the money is untouchable.
- What happens if something goes wrong after the donation settles?
- DonaOnchain cannot reverse or recover funds on a donor’s behalf. That is the trade: the wallet and the ledger are public precisely so you can watch the money instead of trusting our internal records.
Verifying it
- What exactly can I verify onchain?
- Two steps, both public. First the donation itself: the transaction, the amount and the hash, paid into Voulti’s settlement contract. Then the withdrawal from that contract into ReFi Colombia’s wallet, listed in the movements above. The blockchain cannot by itself verify an offchain purchase or the final use of converted funds — that half rests on ReFi Colombia’s public reporting.
Donating
- Which tokens and networks can I use, and are there fees?
- USDC and USDT on Celo, Base, Arbitrum One, Polygon and BNB Chain. A 1% payment-processing fee is deducted at settlement, and network gas is paid by you.
- Do I have to give my name?
- No. Donating by name is offered first because a ledger with real names on it is what makes others want to be on it — people, companies and DAO treasuries backing this publicly can appear beside their contribution. Choose Anonymous instead and your amount and transaction stay public onchain, while your name never appears on this site.
- Is the donation tax-deductible?
- No. DonaOnchain is not a registered charity and contributions are not being presented as tax-deductible donations.
The certificate
- What is the contribution certificate?
- An optional shareable certificate in your name, registered on Celo and linked to your contribution. Only donors who ask for it get one — it is never issued by default. It does not certify how the funds were later spent.
